Unwritten rules in football

Deliberately adversarial institutions are highly regulated, and closely monitored. But for a variety of reasons there can’t be an effective or enforceable rule against every kind of behavior that seems “just wrong.” So there are generally a lot of “unwritten rules” and various written and unwritten “codes of honor” that participants expect each other to adhere to.

“We’ve got to get the snap thing worked out,” Romo told reporters after the game. “We’ll get that worked out. We’ll tell the league and see if that’s something that can be fixed because you’re not supposed to be able to do that. So we’ll see. But we can’t have that happen. We shouldn’t have been in that situation.”

Now, as it turns out, the NFL does have a rule against this behavior. This shouldn’t be surprising, since the NFL, more than any other major sport, is prepared to try to solve any problem with a new rule and close monitoring. But this is clearly one of those rules that’s difficult to enforce. It relies on players recognizing that this is “not cricket,” as they say.

With any post on “unwritten rules in sport/institution X” we will finish with the same general questions: What examples are there of unwritten rules in other deliberately adversarial institutions that are similar to defensive players in football mimicking the offensive quarterback’s snap count? And why, exactly, is this kind of tactic unseemly?

(Incidentally, there are plenty of examples in nature of predators mimicking signals its prey species uses in order to lure them to their demise. So much for natural justice.)
